Michel Juneau-Katsuya, a security analyst and former CSIS intelligence officer, told CBC News that the Chinese government was the likely culprit, adding that China sees Canada as "a land of opportunity to get natural resources that they need so, so much."
The disclosure of the cyberattack comes on top of week filled with cybersecurity news.
On Tuesday, the U.S.Deputy Secretary of Defense William J. Lynn told the RSA information security conference that the Defense Department would like to extend its cyberdefenses to private-sector critical infrastructure as part of its Cyber 3.0 security strategy that will partly rely on public-private partnerships to help secure cyberspace. (Watch Lynn's address below.)
During his speech, Lynn noted that both government and commercial networks are under attack, referencing recent attacks on the Pentagon, Google, NASDAQ, and the oil and gas industry and underlining the shared mission of cybersecurity.
"It is clear that securing our networks will require unprecedented industry and government cooperation," he said. "With the threats we face, working together is not only a national imperative. It is also one of the great technical challenges of our time."
This announcement was followed today by a British government report that estimated cybercrime cost the country £27 billion a year.
Both the United States and the United Kingdom list cyberthreats as a top national security concern that each country must guard against.
